Concrete anti-cracking and anti-seepage admixture and preparation method thereof
The invention relates to a concrete anti-cracking and anti-seepage admixture and the preparation method thereof. The concrete anti-cracking and anti-seepage admixture comprises the following raw material components in percentage by mass: 0.1-1% of ammonium pentaborate, 1-10% of polyaluminum sulfate, 3-5% of ammonium sulfate, 1-5% of potassium oleate and the balance of water. The concrete anti-cracking and anti-seepage admixture provided by the invention is low in doping amount and good in anti-cracking and anti-seepage effect, has no negative influence on the comprehensive performance of concrete, can obviously prolong the service life of the concrete, can reach the anti-seepage grade of P12 when the doping amount reaches 1-5%, has the service life of 20 years without seepage, and can replace the existing anti-seepage and anti-cracking products.
本发明涉及一种混凝土抗裂抗渗外加剂及其制备方法，该混凝土抗裂抗渗外加剂其原料组分及其质量百分含量如下：五硼酸铵0.1‑1％，聚合硫酸铝1‑10％，硫酸铵3‑5％，油酸钾1‑5％，余量为水。本发明提供的混凝土抗裂抗渗外加剂掺量低，抗裂抗渗效果佳，对混凝土综合性能没有负面影响，可以明显改善混凝土的使用寿命，掺量达到1～5％时，抗渗等级可以达到P12，寿命可以做到20年不渗漏，可替代现有抗渗抗裂产品。
